摘　　要：20 0 1年 1～ 3月共分 3期 ,在北京城市地区大气边界层进行了大气化学和气象现埸观测。结果表明 :北京城市低层大气中主要的气体污染物是NOx,其次为SO2 ;各高度SO2 和NOx 之间的关系有较好的一致性 ,NOx 大约为SO2 浓度的 2倍或 2倍以上 ;污染源排放是造成北京城市低层大气空气污染严重与否的主要原因之一 ;同一季节中空气污染状况很大程度上取决于天气条件 ;NO2 /NO和NO之间有着较好的负幂指数相关关系 ;The field experiment of atmospheric chemistry and ABL meteorological measurement was carried out from January to March 2001. The result shows that the major air pollutan is NO x and the second is SO 2. SO 2 and NO x concentrations at various levels are correlated well. NO x is about 2 times as much as SO 2. The source emission was main reason for air pollution in Beijing. The air pollution in same season is, to a great degree, depended on weather. There is good correlation of minus power index between NO 2/NO and NO, which does not vary basically with location,time and altitude. The variation trends of air pollutants at different altitudes and locations with time show good consistency.
